Another Function problem

[queenbuc]

If the revenue function for a rib place is r(x)33/16x-42 and the cost function is c(x)=33/32x+47, how much profit or loss will be made each hour when 95 dinners are produced and sold?

Hint: Profit is the difference between revenues and costs.

Thanks so much.... I don't know why that was so hard to me.
